1. Product Overview

3. Setup and Installation

Follow these steps to set up your KOQICALL Window Intercom System:

1. Position the Main Unit: Place the main unit (with the gooseneck microphone) on the staff side of the counter or window.
2. Position the External Speaker: Mount the external speaker (sub-station) on the customer side of the glass or partition using the provided double-sided tape. Ensure it is securely attached.
3. Connect the External Speaker: Connect the cable from the external speaker to the EXT port on the back of the main unit.
4. Connect Power: Plug the power adapter into the POWER socket on the back of the main unit, then plug the adapter into a standard electrical outlet.
5. Power On: Press the red Power ON/OFF button on the main unit to turn on the system. A red indicator light will illuminate.

Only one wire is needed to connect the main unit and the external speaker, simplifying installation.

4. Operation

The intercom system provides hands-free, two-way communication. Here’s how to operate it:

• Two-Way Communication: Once powered on, the system allows for simultaneous conversation between the main unit (staff side) and the external speaker (customer side).
• Volume Adjustment: Use the volume knobs on the back of the main unit to adjust the microphone volume for the main unit and the speaker volume for the external speaker independently.
• Mute Function:
  • The I-MUTE button (left, silver) mutes the main unit's microphone, preventing the customer from hearing the staff.
  • The O-MUTE button (right, silver) mutes the external speaker, preventing the staff from hearing the customer.
• Recording Function: The system includes a 'REC' socket on the back for connecting an external recording device to record conversations, if desired.

5. Maintenance

To ensure the longevity and optimal performance of your intercom system, follow these maintenance guidelines:

• Cleaning: Use a soft, dry cloth to clean the surfaces of the main unit and external speaker. Avoid using abrasive cleaners or solvents.
• Environment: Keep the system in a dry environment, away from direct sunlight, extreme temperatures, and excessive dust.
• Cable Care: Ensure all cables are not kinked or pinched, which could damage the wiring.

6. Troubleshooting

If you encounter issues with your intercom system, please refer to the following common problems and solutions:

• No Sound:
  • Ensure the power adapter is securely connected and the unit is powered on (red indicator light).
  • Check that the external speaker cable is firmly plugged into the EXT port.
  • Verify that the volume knobs for both the main unit and external speaker are not set to minimum.
  • Ensure neither the I-MUTE nor O-MUTE buttons are activated unintentionally.
• Distorted or Unclear Sound:
  • Adjust the volume levels on both the main unit and external speaker.
  • Ensure the microphone on the main unit is positioned correctly towards the user.
  • Check for any obstructions around the speakers or microphones.
  • The system has a special sidetone processing chip and movement noise function to improve noise effectively. If distortion persists, ensure the environment is not excessively noisy.
• Intermittent Connection:
  • Check all cable connections for looseness.
  • Inspect cables for any visible damage.
